GRAVITY PLUMB AND LEVEL.

Specification of Letters Patent.

Application filed July 15, 1905. Serial No. 269,896.

objlect to which the level may 'be ap lied.

he object of the invention is a evice of the kind described in which the index hand may be uickly read from either side of the level and a further objeetis toprovide a device of the kind in which a single index hand travels about a two-faced dial, the dial faces being visible from opposite directions.

.place by screws '1 In the accompanying drawings,-Figure l is a side elevation, the level being partly broken away. Fig, 2 is a transverse section tiakpn substantially across the center of the in these drawings A represents a level which is rovided with a centrally circular opening t e edges of which are beveled and u on each side of the level a circular flanged p ate B is set in the level surrounding said 0 ning, the flanges of the plate resting upon t e bevels of the mar inal portions of the Said 0 enilig. These p ates not only protect the e ges of the opening but also serve to hold the various parts to be hereinafter described in' place, and in order that the arts may be readily removed when desired the plates B are held in position by means of screws 0. Within the opening is fixed a rim dial, said dial bein V-shape in cross section, one piece of the dial fitting snugly against the walls of the o ening, and being secured in The wall of the opening is also rabbetcd upon opposite sides of the dial D thus forming two annular shoulders upon opposite sides of said dial ring and g ass dis s J are fitted in the opening, each disk being held between one oi said shoulders" and one of the plates B. The inner face of each disk J is centrally recessed to form bearings I for the ends of a needle shaft G. Upon this shaft is hung a semi-circular wei ht E which carries an index linger F. the sai( finger rotating about the shai' t G in alinement with the projecting edge or apex of the V-shaped dial ring D. The ring upon its two visible opposing faces is raduated in. any desired manner and it will be obvious that by adjusting the parts when assembled so that when the level A is in an absolutely horizontal plane that the index. linger F will point to zero and ii the dial ring is u'operly graduated any inclination out of the 10112011 tal of the level A will be accompanied by a proportional swinging movement upon the art of the index finger l which will show by its travel along the edge of the dial ring the extra number of disks out of the horizontal of the level A.

Havin thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 2-- a level havinc a circular opening, the walls of which are rdbbeted to form annular shoulders, the marginal portions of said opening being beveled/circular flanged plates surrounding said opening, the flanges oi the plates bearing, upon the beveled portions, glass disks held in said opening between the flanges and shoulders respectively, V-shaped in cross section said ring being'; se cured in the opening'between the glass disks, bearings beingiormed in the inneriaces of said glass disks, a shaft mounted in said bearings, a weight suspended from said shai't, and an index finger carried by said weight and. traveling along "the projecting ed e of the dial ring, the visible laces suitably graduated.
